Abstract [Cu(hyetrz) 3 ](CF 3 SO 3 ) 2 ·H 2 O [hyetrz = 4‐(2′‐hydroxyethyl)‐1,2,4‐triazole] represents the first structurally characterised ferromagnetically coupled Cu II chain compound containing triple N 1 , N 2 ‐1,2,4‐triazole bridges. catena ‐ [μ‐Tris{4‐(2′‐hydroxyethyl)‐1,2,4‐triazole‐ N 1 , N 2 }copper( II )] b…
The room-temperature synthesis of a macro-mesoporous silica material during the natural creaming process of an oil-in-water emulsion is reported. The material has 3-dimensional interconnected macropores with a strut-like structure similar to meso-cellular silica foams with mesoporous walls of worm-hole structure. The…
The synthetic layered silicates Na+-ilerite (Na2Si8O17·nH2O), Na+-magadiite (Na2Si14O29·nH2O), and K+-kenyaite (K2Si20O41·nH2O) were converted to the corresponding layered silicic acids (silicas) through the stoichiometric replacement of the gallery alkali metal ions with protons. The protonated derivatives were subse…
A water-soluble and self-doped conducting polyaniline graft copolymer, poly(styrenesulfonic acid-g-aniline) (PSSA-g-PANI), was first synthesized and its electrical properties were investigated.

With the increase in current densities, electromigration has become a critical concern in high-performance designs. Typically, electromigration has involved the process of time-domain simulation of drivers and interconnect to obtain average, root mean square (r.m.s.), and peak current values for each wire segment. How…
Variational cluster calculations and Monte Carlo simulations are applied to hard-body board-like models of biaxial molecules forming liquid crystalline phases. The molecular long axes are assumed for simplicity to be fully oriented. Depending on the extent of transverse anisometry in the molecular shape, these systems…
The trehalose-phosphate phosphatase (TPP) was purified from the cytosol of Mycobacterium smegmatis to near homogeneity using a variety of conventional steps to achieve a purification of about 1600-fold with a yield of active enzyme of about 1%. Based on gel filtration, the active enzyme had a molecular weight of about…
Abstract Interpenetrating polymer networks (IPNs) based on different ratios of a modified bismaleimide resin (BMI/DBA) and cyanate ester (b10) have been synthesized via prepolymerization followed by thermal curing. A systematic thermal degradation study of these new BMI/DBA‐CE IPN resin systems was conducted by thermo…
The conversion of porphyrazine-diamine derivatives into either seco-porphyrazines or porphyrazine palladium or platinum complexes has a profound effect on the photophysical and photochemical properties which has relevance to the design of switchable agents for photodynamic therapy and other applications.
Cation tracer diffusion of 138La, 84Sr and 25Mg in polycrystalline samples of doped lanthanum gallate, La0.9Sr0.1Ga0.9Mg0.1O2.9, was investigated by SIMS for temperatures between 900 °C and 1400 °C. It was found that diffusion takes place through the bulk and along the grain boundaries. The bulk diffusion coefficients…
Three point bending specimen was made from commercial alumina and Al2O3/SiC composite ceramics. A semielliptical surface crack up to 500μm in diameter (aspect ratio≈0.9) was introduced on the test specimens. Basic crack-healing behavior was systematically studied as a function of crack-healing temperature, environment…
Hybrid terpolymers consisting of polyhedral oligomeric silsesquioxanes (POSS), N,N-dimethylacrylamide, and bipyridine monomer were synthesized by a common radical polymerization method and their structures and thermal properties were studied by FT-IR, 1H NMR, DSC, TGA. The thermal stabilities of the hybrid terpolymers…
Both reliability and performance of electronic systems can be seriously affected by dynamic thermal and electro-thermal effects that take place at the device, chip, package, board and system levels. The marked trend towards miniaturization down to the nano-scale, increases problem complexity due to the large number of…
To answer the question of whether condensation occurring on the inner surface of a waterproof breathable fabric or moisture content within such a fabric has the greater effect on water vapour transfer rate experiments were conducted using two different types of waterproof breathable fabrics under isothermal and non-is…
ABSTRACT: Whey protein isolate (WPI) films have proven to be excellent gas barriers in previous studies, making them potential coatings for fresh produce. WPI‐coated apples and controls were stored at 20 °;C under RH's ranging from 54 to 92%. Results showed performance of WPI coatings depended on the environment RH. T…
Nickel and cobalt heterocubanes have been synthesised from dinuclear complexes. The use of 8-hydroxyquinaldine leads to a rhombohedral distortion in two faces of the cubes. Both cubes were studied by paramagnetic NMR, which shows that they are stable in solution. Magnetic measurements show that the coupling within bot…
The liposomalization and polyethyleneglycol (PEG) modification of antitumor agents prolongs their circulation in the blood and increases their accumulation in the tumor. It is expected that modification of the liposome surface with PEG-Lipid will prevent connection of liposome and tumor cell, so we examined the effect…
High quality inorganic fullerene-like boron nitride hollow spheres (100-200 nm) have been successfully synthesized via a simple chemical route with a 30-40% yield of BN hollow spheres.
The temperature and frequency dependent damping behavior of Ni added Mn–Cu alloys were investigated. Ni addition not only increased the magnitude of the phase-transformation damping peak, but also decreased its frequency dependence. A decreased transformation temperature was found in the Ni added Mn–Cu alloys under th…
